Description The article describes how to clear disk utilization from the WAD process.
Scope FortiGate.
Solution

To check utilization of the partition, see step 4 in Technical Tip: FortiGate hard drive and SMART status.

 

If the WAD process is consuming too much memory ('diagnose system top-mem'), use the following debug commands to clear the partition.

 

diagnose debug enable
diagnose test app wad 21200
diagnose test app wad 98

 

Wait for a while, and then disable the debug commands.

 

diagnose debug disable

Check the partition utilization with 'fnsysctl df -k' and confirm the partition has been reset.
